| abstract |
The invention provides a method and composition for lubricating and improving the processability and releasability of rubber and plastic without adversely affecting other desirable properties of the rubber or plastic such as adhesion, tack, modulus and tensile strength. According to the invention lubricating agents, which are normally incompatible with rubber or plastic, causing serious defects, e.g. silicones and fluorocarbons, can be incorporated into rubber or plastic without defects, by preblending them with a peptizing agent prior to their incorporation into the rubber or plastic. |
